fre ALL WHQM IT'MAY CoNcEnN;

Be it-known that I, ROBERT O. LOWREY, of Saratoga Springs, in the county of' Saratoga, and State of New York, have invented certain new and useful Improvementsin Spring-Bed Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to `the'accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur. v

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention relates tcspring-bed bottoms, and consists of a. very simple, cheap, and convenient method of applying the springs to the slats at the head and at the foot of the bedstead, and, at the same time, makin those at the head stiffer than those at ,the foot. 1 i

Inbed-bottoms, as ordinarily constructed, the springs at the head are ofthe same strength as those at the foot, and as there is more vi'eightin the upper portion of the body than in the lower, the springs at the head are more compressed-than at the foot, when the bed is in use. i v l s In my construction I make the springs at the foot considerably weaker than those at the head, and in this way give-the bed-bottom an incline towards the foot.` In the drawings- Figure 1 is a top plan view.

Figure 2 is allongitudinal vertical section on the line :c :z: of ig. 1; and

Figures 34, and 5 are views of the springs detached and enlarged. s

I first construct a bedstead-frame, A, in the ordinary manner, and then across the-interior of the head and foot-piece ot' the frame I attach a series of springs, B C, made of ordinary brass or iron spring-wire, and shaped or formed as clearly shown in figs. 3, 4, and 5. Each spring is made of a single piece of wire, formed as shown in all th`e figures, with the 'ends' b bent at right angles, so as tobe driven into the bed-frameiias shown in fig. 2, n and, at a short distance from the ends, turned into loops largeenough to receive screws d, as shown in iig. 4, for i the pui'pose`oi` fastening them rigidly to theeframe A. The portion of thewirc between `the loops for receiving the screws irl," I first coil, as shown at z in iig. 4, and then bend the remainder of it in the form of a tongue, Las shown in all the iigures, and with a. hook, afan theextreme end of the tongue, as shown'in'figs. 1 and2. When the springs are being constructed, I make those intended for4 the headof the bedstead of heavier wire than `the ones to bc'used for the foot, and consequently stiffer. After the springs are attached-to the frame A, as sho'ivn in figs. 1 and 2, I pass the hook d up through rectangularopenings, e, in each end of the slats D, as shown in the sameflgures. i The slats D will then rest upon the shoulders e of the springs, and be supported b y them.V If the slats become sprung, or for any other reason it may be desirable to turn them over or remove them, itis only necessary to press down the slat until the hook on the spring is.released,and thenhold the spring stationary'- and lift off the end of the slat. The other end of thesslat may then be released by simply unhooking it.' The. slat may then be turned over, or another slat substituted in its'place. Y -As the springs at the head are made stiii'erthan' those at the foot, they will yield ,less when. the bed is used, and, under the pressure, the slats will incline, as shown in fig. 2 by the red lines.- V'The springs B C may be stiifened by passing an iron rod through the coils and fastening it to them. By this means they Wouldact more together, and vvnuld beheld in their res'pective positions. The arms e of the springs B' G are made suiiiciently far apart to allow the ends of the slats D to pass between them, as shown in'g'. 1. s

By these arrangements of the springs and slats, I am enabledvtomake a simple, cheap, durable, and convenient spring-bed bottom.

Havingthus described my invention, what I claim, is f l .A bed-bottom, consisting of va. series of independent slats, D, suspended on the stili' springs 13, at-the head, andthe weaker springs C, at thehottom, substantially asJ shown and described. i i
